The effect of low salinity on phenoloxidase activity in the Sydney rock oyster, Saccostrea glomerata
This study tested the effects of low salinity on phenoloxidase activity in Sydney rock oysters (Saccostrea glomerata). Phenoloxidase is a key component of the immune system in S. glomerata. Previously, we have shown that decreased phenoloxidase activity is associated with susceptibility to fatal QX disease. In the current study, laboratory-based experiments were used to identify factors that co...
متن کاملTranscriptome Analysis of the Sydney Rock Oyster, Saccostrea glomerata: Insights into Molluscan Immunity
BACKGROUND Oysters have important ecological functions in their natural environment, acting as global carbon sinks and improving water quality by removing excess nutrients from the water column. During their life-time oysters are exposed to a variety of pathogens that can cause severe mortality in a range of oyster species. Environmental stressors encountered in their habitat can increase the s...
متن کاملRelations between variable rates of growth, metabolic costs and growth efficiencies in individual Sydney rock oysters (Saccostrea commercialis).
Rock oysters from a mass selection trial were compared with wild-caught (control) oysters of the same age to determine the physiological basis for faster growth rates amongst the selected individuals, and to describe the associated flexibility in phenotypic traits of feeding, metabolism and growth. In confirmation of earlier studies, fast growth was associated with faster rates of feeding, redu...
متن کاملBiomonitoring Total Mercury in the Persian Gulf Using the Rock Oyster (Saccostrea cucullata)
This study is an attempt to evaluate the biomonitoring capabilities of rock oyster, Saccostrea cucullata, for mercury (Hg) pollution. The oyster and sediment samples were collected from 10 rocky habitats of Qeshm and Hormoz Islands in the Persian Gulf. The concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. Biot...
متن کاملThe role of phenoloxidase suppression in QX disease outbreaks among Sydney rock oysters (Saccostrea glomerata)
The paramyxean protozoan, Marteilia sydneyi, is the etiological agent of QX disease in Sydney rock oysters (Saccostrea glomerata). QX disease affects the farming of oysters in Queensland and on five rivers in New South Wales (NSW), Australia. Disease outbreaks occur during summer months (January to April) and are associated with high mortality rates (up to 98%), which limit the growing out peri...
